Trek has created a proprietary rear suspension design called ABP (active brake pivot) that isolates suspension and braking so you won’t lose travel or lock up due to the force of the motor on the chain.

Electric Bike Review
Trek Powerfly FS 9 Equipped Review

oct. 2020

Price: $5999.00 | Model Year: 2021 | A premium

Observations
  • A premium "do anything" full suspension electric bike that's equipped to handle pavement, trails, light mountain terrain, rain, shine, day, or night conditions. Available in five frame sizes for optimal fit, the XS and S come with 27.5" wheels and the M, L, and XL come with 29" wheels. Sold through one of North America's largest network of dealers. Trek and Bosch provide excellent support and warranty.

  • Custom made extra-wide plastic fenders are durable and quiet, very capable in off-road conditions. A sleek and sturdy rear rack provides 25kg (55lbs) of cargo capacity with pannier hangers on both sides and a removable top platform for trunk bags. Puncture resistant tires also feature unique black reflective stripes that combine safety with aesthetics.

  • Downtube-integrated battery pack and mid-drive motor keep weight low and center. Trek designed a "RIB" battery casing includes a handle for safe removal and transport. The battery doesn't rattle, and it can be charged on or off the bike with the fast 4 amp charger. Peformance Line CX motor is the most powerful from Bosch, but lightweight with a magnesium casing.

  • Highly adjustable air suspension front and rear with 120mm and 100mm travel respectively. Boost hub spacing and thru-axles increase wheel strength. Extra large 203mm hydraulic disc brakes with heat sinks and alloy cores deliver incredible stopping power. The biggest trade-offs here include the high price, smartphone display (that some may not like), louder motor operation, and increased weight (due to the high capacity battery and accessories).

Flow Mountain Bike
Tested: Trek Powerfly LT9

mars 2019

 This isn’t the first time you’ve ridden this bike, right? Correct. We attended the launch of this bike last year, but we always prefer to test bikes on home soil in Australian conditions. We went deep on the tech details, so make sure you take a look at our First Impressions piece and video …

Points forts
  • An incredible technical climber.

  • Built tough!

  • Smooth power delivery.

  • Excellent Bosch eMTB motor mode.

Points faibles
  • Slow speed manoeuvrability isn't great.

  • Quite heavy.

Review: Trek Powerfly LT 7 Plus

janv. 2019

If I had to think of one common theme that continually came up during our time with the Powerfly, that would be it—too damn fun. Over the months we’ve had this bike, we’ve done it all and it does it all with ease.
